FLUSHING-CISTERN.

Specification of Letters Patent.

Patented J an. 19, 1915.

Application filed February 19, 1914. Serial No. 819,829.

To all whom it may concern:

Be it known that I, AoHILLn VALo1s, a subject of the King of Great Britain, and resident of the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Flushing-cisterns; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to flushing cisterns and the object is to devise a simple and cheap device for attachment to the ordinary float valve movable-siphon cistern whereby the same can be converted into the leverfloat fixed siphon type at very little cost.

A further important object is to provide means for relieving the strain on the inlet valve and to consequently prolong its life.

To attain these objects a new leg is inserted in the siphon and securely fixed to the tank while the ordinary float is taken away and a water displacement lever-float substituted therefor to which said lever the pull chain is connected. When the chain is pulled, the water in the cistern is displaced until it rises suflicient to start the siphon. One of the chief features of the invention however is an adjusting arrangement for the lever-float and an adjustable stop whereby the height limit of the water in the tank can be regulated and whereby the strain is taken off the inlet valve when the float rises.

The invention will be better understood with the aid of the accompanying drawings in which Figure l is a vertical sectional view of a flushing cistern according to my invention. Fig. 2 is an inside view of the front of the tank showing the slotted guide and Fig. 3 is a sectional perspective View of the inner end of the lever-float.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 indicates the cistern into which leads the inlet pipe 2, the latter being coupled to the ordinary inlet valve 3 in the usual manner. The siphon 4 is provided with a long leg 5 extending through the bottom of the cistern 1 and securely fixed in said bottom by a nut 6.

7 is the lever-float preferably of rectangular section and converging toward the inner end where it is provided with an inwardly extending lug 8 to which a connecting bar 9 is pivoted at 10 intermediate of its length. This bar 9 corresponds to the inner end of the ordinary float lever and being pivoted at 11 to the valve 3, operates to press up the valve plug 12 in the ordinary manner. The outer end of the bar 9 however is adjustably clamped to the lug 8 by the bolt 13 passing through the arc-shaped slot 14, in said lug, thus permitting the angle of the bar 9 in relation to the lever-float 7 to be charged. The outer end of the lever-float 7 is provided with an off-set leg 15 extending through a slotted guide 16, the latter extending vertically up from the outer end of the cistern and adjustable as to its height by a bolt 17 passing through the slot in said guide. 18 is a rubber bufl'er secured to said guide at the upper end.

In the use of this invention, the chain 19 is pulled which brings down the lever-float 7 and displaces the water in the cistern until it rises suilicient to start the siphon. The chain is now let go and the cistern will empty by way of the siphon 4, but it must be pointed out that in this class of cistern when the chain is let go there is usually considerable strain on the inlet valve as the float 7 springs violently upward. Therefore the purpose of the adjustment of the slotted guide 16 will be apparent, it being adjusted so that the leg 15 contacts the buffer 18 as the valve plug 12 takes its seat so that there will be a limit of movement at the inner end of the lever-float by the valve plug 12 and at the outer end by the buffer 18, thus avoiding strain and prolonging the life of the inlet valve. The height of water in the tank -may be regulated by slackening the bolt 13 and adjusting the lever-float up or down by swinging it on the pivot 10, but after again tightening the bolt 13 the slotted guide 16 should be correspondingly lowered or raised.

It will be obvious that the features of adjustment which form the most important part of this invention are not only adaptable to the rigid siphon type of cistern wherein the float forms the starting lever by displacement, but they are also applicable to the ordinary movable siphon cistern. However, they are particularly suitable for the first mentioned type in order to avoid the strain caused by the violent upward bounce of the lever-float when the pull chain is released.

WVhat I claim is A flushing cistern of the fixed siphon type having an inlet valve adapted to be closed by the raising of the valve stem, a lever in the form of a hollow float adapted to be raised by the Water and having an adjustable connection at its inner end to said valve whereby said valve is closed by the raising of the float, a slotted guide secured to the side of the cistern, an off-set pull rod reach- Gopies of this patent may be obtained for five cents each, by addressing the ing from the outer end of said float through the slot in the guide, a buffer secured to the guide at the top of said slot and means for adjusting the height of said guide in relation to the cistern whereby the inlet valve is relieved of any undue strain.

Signed at the city of Montreal, Quebec, Canada, this eighteenth day of December,

AGHILLE VALOIS.
